Hi guys, i am moving to a new address that's served by optimum online. For TV, i want to get the cheapest package (just basic channels + their HD counterparts).
The prime mover for flexion of the shoulder muscles used are the following: 1  Pectoralis Major Clavicle. 2  Anterior Deltoid. 3  Biceps Brachii Short Head. 4  Coracobrachialis.
The shoulder is the most complex joint in the body. The tremendous amount of flexibility in the arm that we take for granted is because of the complexity and shallow nature of the shoulder joint. The shoulder joint movement is controlled by muscles from the body to the shoulder blade, or scapula, muscles from the scapula to the arm and muscles from the body to the arm. To keep the shoulder stable, there are four so called rotator cuff muscles whose primary task is to keep the shallow joint in place.
